It started a supposed flu virus, and spread quickly because nopony thought of it as more than a simple bug. But it wasn't just the flu. It was a virus that turned its victims into mindless flesh-eating monsters. Fortunately, the disease isn't airborne, so there are some survivors. Unfortunately, lots of the remaining survivors don't take kindly to strangers. Even if they are royalty. The terrible infection, known as "The Resurrection Plague", is ravaging all of Equestria and the mane 6 , Spike, Princess Luna, and the CMC, without the help of the Tree of Harmony, are the only ponies, (and dragon), who can find a cure. And nopony will stand in their way. Or will they?
